hi just put tomie poncams 256 in last week been haveing problems idleing and at times the car dies. i have a JWT ecu in right now thats tuned for hks 264 cams but ive been running stock cams just befor last week. ive cleaned the iac,put a buddys maf in to see if thats the problem checked volts on the tps checked the timming three times and checked for vac leaks the only thing i havent done yet is check/clean or replace my o2 any ideas?

Does the car run good besides idle? If not id say your 1-2 teeth off on the intake cam. The tune shouldnt matter much. Also are the lifters noisy? Could be a difference in height for.the hydro lifters and may need to be re bleed (hydro lifters don't initially adjust themselves)

yea i did all of that when changing the cams i couldnt see why it would run the way its running because of the lifters not being bleed. and it feels more of a senser.yea i know tune isnt a question eather because i had bigger cams in it before these im going to try the o2 tonight and see if it gets better.

Its not the o2, nissan ecu doesn't read the o2 during idle.

well even checking the timing three times 4th was the trick lol one tooth off
